PATEN '1J Application led July 22, 1909. Serial No. 509,072.

To all whom; it mag/,concern Be it known that I, ERNEST R. Vienne, ofthe city of Montreal, in the Province o't' Quebec and Dominion ofCanada, have invented 5 certain new and useful Improvements in MetalWindow-Sashes, of which the following is a full, clear, and exactdescription'.

This-invention relates to met-al window sashes, and more particularly tosashes in railway cars. The main object of the invention is t-o providea sash frame of seamlessk metal tubing which will be very durable andefficient, and yet light in weight and com- 15 paratively inexpenslve.

The inventiorconsists essentially of a window sash of metal bent intotubular form,` with a flange at the glass o1' panel side combined withretaining strips or that hold the parts in position. Y In the drawingswhich illustrate my in` ventiom-Figure 1 is a partial elevation of awindow construct-ed according to my in- 2 is a cross sectional view onthe line 5-6 of Fig. 1 showing one method of forming the corner. Fig. 3is a similar view on the line 9-10 of Fig. 1, showing another method offorming-the corner. Fig. 4

In the above defined figures, a plurality of seamless tubular sectionsof metal formed into a sash of vany desired con- The sections areprovided with inwhich the glass panel 13 is clamped through `itsperipheral setting 14 by the beadstrip 415. The setting 1,4 may be ofanysuitable and the beadstrip 15 of'any' that shown in the drawings.' Thetubular sections 11 may be united at the corners of the sash either by amiteror by a mortilse t e sections after being brought together areriveted to a casting 16 which holds the cor- ,the mortise is 11designates'v the entire internal thicknessofrt-he section and the tenonis formed of .a tubular inem` ber 17, of adequate thickness andstrength,

the side stiles` and riveted there, as seen in" the right hand corner ofFig." 1.'

As the metal of which the sections are constructed is of necessity toothin to be threaded' for the receptionolf the screws 1 8,

which secure the bead strlps 1 I provide a Vcomparatively thick fillerstrip'19nthreaded' f 60,A

to receive` the screws. The filler strip ex# tends into the hollowpressing the inner w cesses formed in the'abutting sur ller, as seenat'20, in Figs. 2 and 4. The liller is then 'turned under thetpanel seatand then downwardly at the `required angle to bring the portion thatportion of the, bead stri which the screws 18 pass. desired to secure a.handle,
